LOCKING DEVICE Fon Moron-VEHICLES.

i To all whom z't may concern: f

' The invention `relates Be it known that I, Enivannl). B'AIRD, a

resident of Evanston, in the county of Cook -and'State of Illinois, haveinvented certain new and useful Improvements in Locking Devices vforMotor-Vehicles, of which the following is a full, clear,l and exactdescription." i

to locking devices for motor vehicles. 'l

One object of the invention is to provide an improved locking-device forpreventing a motor-vehicle from being'stoln by making it impossible tosteer the vehicle. Another .object of the invention is -to provide animproved' steering wheel-lock whichis simple in construction and may bereadily applied as an* attachment to steering wheels of usualconstruction. A still further object of thel invention is to provideaniiiiproved lock vfor steering devices which can be produed at a lowcost and which can he easily applied' tothe vehicle 'The inventionconsists in the several novel features hereinafter set forth and moreparticularly defined by claims at the conclusion,

hereof.l

In the drawings: Figure 1 is a side elewheel 9 comprising ya rim 10,spokes 11 and hub 12, which is secured to a steering shaft 14. T hesteering shaft extends through a hollow fixed column 15 and the hub 12lis usually secured to' the upper end of ysaid shaft. The spokes 11 andhub 12 are usu-j ally integrally formed, so that a lockin de-'v viceapplied to the spokes will effectively lock the \'vlieel againstrotation. usually secures the huh 12 to the shaft 1.4i

A hand 17 which may he formed of sheet metal, fits snugly around thecolumn 15 and is provided with flanges 18. Bolts 19 pass through theseflanges and are' adapted to contract `the sleeve to firmly ,clamp it inposition on the steering column 15. 'This band exemplifies a clampadapted to be secured to the steering column and which is device isadapte'dfor ati tachinent to a steering device of usual cOn-A struction,as exemplified by the steering.

surrounded by the locking-sleeve 20, so that the band will beinaccessible and' cannot be loosened while the lsleeve is on the band.vSleeve 2() is slidable longitudinally s0 and is' provided with upwardlyextending i teeth or lugs 2l -adapted to pass between, the spokes 11 ofthe steering wheel and is disposed adjacent the hub 12, so that when theteeth or lugs are moved upwardlybetween the spokes, thesteering-wheel-cannot be rotated. These teeth are also adapted to coverthe securing pin liwhe'n'they'. arc in operative position, sothat thepin cannot be removed. The locking sleeve is 70 provided with 'a chamber2 2V forthe reception'. ofthe fianges .18 of the clamp and the bolts 19,and this connection prevents relative rotation of the clamp and the'locking-z -l sleeve 2.0. The wall of the sleeve is extended 7 f5around'this spaceand to 'form a st0p23 y adjacent the lowerfend of thesleevea'nd 'is' provided with an eccentric pin '25 which 1s adaptedtoengage the lowerendy 26ofi'a locking member 27, the upper en d "tofwhich' is secured, as at 2S, to the wall off Vsleeve 20. Member 27 isresilient 4and provided. with a tooth 29 adaptedt enter either of tivonotchesBO and 31 in the flanges of the clamping hand to lockthey sleeve2O in operative and inoperative positions, respectively. o

Flat slightly bowed resilient s'trips'32 andV 33 are held in pockets 34land formed in` the sleevej 20 to prevent rattling in event 95 that thesleeve 20 does not fit snugly on'the clamp. 1- -v When tooth'29'on'locking-member 27 is disposed in notch v31, the sleeve, 2Q will bemember tohold the sleeve so that thespolge ofthe steeri'i'ig-wheel willhe free tobe -tated to steer the vehicle.' l/Vhen the steering-wheel `isto he'loeked, the-key willv be inserted into the cylinder-*lock 24' andturned to cause the eccentric pin 25 to move the-lower end 26 of member27 outwardly and Withdraw tooth 29 from notch 31. The sleeve 20 can thenberaised until the tooth 29 passes into notch 30. The key can vbe 110withdrawn after sleeve 20 has been released from the notch 3 1 and movedupwardly sii i sufficiently to cause tooth 29 to ride on the outer edgeof flanges 18. When tooth 29 has passed into notch 3Q, the teeth or lugs21 .will be locked between the spokes 11 of the tion of said column;

steering-wheel, so that lit'will be impossible to steer the vehicle andconsequently impossible to steal it. To unlock the steering# wheel,cylinderloek 24 will be operated by a key to Withdraw whereupon thesleeve 20 willl be free to fall into inoperative position. Sleeve 20 isat all times held againstrotation by the bolts 19 iitting'in the offsetspace 22. rlhe locking member 27 is at all^timeseffectively inclosedagainst fraudulent manipulation.-

To apply the'device to a steering column', it is only necessary toi'emove the steering wheel from its shaft, then secure the clamp inpositionion the steering column, then slip the locking sleeve down thenreplace the wheel.

The linvention exeinp y lifies alocking device for a steering wheelwhich may be at tached to a column for the steering shaft of` usualconstruction Without the necessity of drilling or otherwise changing theAconstruc- The invention is fnot to be understood as restricted to thedetails set forth, since these may beimodifed within the scope of the a'pended claims-without departing 'from t e spirit and scope of theinvention.
